The stain on your ceiling is not where the leak is.
Finding the actual source — which is rarely where the stain is.
Water does not fall straight down through a roof. It enters at a failure, runs along the underside of the decking or down a rafter until it meets an obstruction, and drops there. By the time it reaches your ceiling it can be many feet from where it got in, which is why patching the drywall directly above the stain achieves nothing at all.
Finding the real entry point is the job. In our experience the great majority of leaks are not holes in the field of the roof — they are at the interruptions. Step flashing at a sidewall that was never woven into the courses correctly. A chimney counter-flashing that has pulled out of its mortar joint. A pipe boot whose rubber collar has perished after a decade of ultraviolet exposure. A valley that was closed-cut with the wrong overlap. Skylight head flashing. A nail that was overdriven at installation and has been working a hole in the mat ever since.
We trace it from both sides where we can — the roof surface and, when there is access, the attic, where the wet path is often visible on the sheathing long before it reaches a ceiling. Then we photograph what we found and show it to you, because you should not have to take a roofer's word for something you cannot see.
And we are straight about the outcome. If the roof has years left, we repair the failure and tell you what to keep an eye on. If we are looking at the fourth leak on a covering that is out of service life, we will say so and show you why rather than sell you a fifth repair.

Roof Leak Repair — common questions
Why is my ceiling stain not under the hole in my roof?
Because water travels. It enters at a failure, runs along the underside of the sheathing or down a rafter until something stops it, and drops there. Following the stain upward usually leads to the wrong place.
What causes most roof leaks?
Interruptions in the roof surface, far more often than the surface itself: step and counter flashing at walls and chimneys, perished pipe boots, poorly detailed valleys, and skylight head flashing. Those are the first places we look.
Can you find a leak that only appears sometimes?
Usually. An intermittent leak that shows up only in wind-driven rain points somewhere different from one that appears in any downpour, and one that appears during a winter thaw generally means ice damming rather than a hole. When the pattern is unclear we can water-test the suspect areas in sequence.
Will a repair void my roof warranty?
A repair carried out to specification should not. Careless work by someone else frequently does — which is one reason we photograph what we find and what we did.
Should I repair or replace?
If the covering has service life left and the failure is localised, repair. If we are on the roof for the third or fourth time and the shingles are curling and losing granules across the field, a replacement is the cheaper decision over any reasonable horizon. We will show you the evidence either way.
